last nite i threw the poly 80/jig on the HF mini just because some other members have had some trouble with theirs on this... i read their directions... then threw them away..
first thing i did was drill the trigger pins... then the trigger holes from the top...
set the fluted bit to 1.25" deep and made all my plunge ins as it should... i had the sweeper running all the time to keep the melted "chips" out of the way.... worked my way around it.... using the outside edges of their jig as my guideplate with the bushing on the bit.
this is overly cautious on my part, but you can always take more out.... putting it back sucks.
i read another member said he tore out the safety pin holding slot so i went real careful around the template and nibbled my way into it... my approach leaves it too shallow and you have to come back & take a little more. im good with that.
ran the HF mini on about 350-400 ish & after about 45 minutes of crawling around on it i had it to the point of taking it out and checking it...
first thing i found was that i had a break thru in the front lower end out to the magwell release section.. not all over but just in 1 spot.. tells me that the casting is not perfectly even.. im a bit concerned over the hammer stop & its impact. so will be keeping an eye on this and dry fire the crap out of it to see if i can create a failure..
casting issues? this was also apparent from the BUBBLES in my FCG area when i got to the bottom. had quite a few of these.
now its down to cleaning up the edges in there and seeing if the FCG fits.
this was ridiculously easy on the HF mini & im sure it would be even easier on my BP/dro set up.... more tonite.
